If you thought renewable energy was the big thing of our times, you’d be only partially right. The bigger thing is energy storage – the key to making renewable energy sustainable and reliable; the key to making it practically useful and more than a fad.
There is a truly huge race on to create cheap storage systems, and the greener they are, the better. For instance, you know quinones? These chemical compounds — pigments that are found in a variety of plants — can be used as the basis of organic molecules to make flow batteries. One team of researchers at Harvard, no less, is working on just that: an organic flow battery that is cheap, environmentally friendly, and easily scalable.
